Resp 17 II
Manual Resuscitators powerpoints
| Question | Answer |
|---|---|
| What are the standard connections | 15 mmID (inside) for ET tube, or trach tube and 20 mmOD (outside)for resuscitation mask |
| Uses for bag | Ventilate patients during CPR, hyperventilate before and after suctioning, ventilate during transport, management of mechinially ventilated patients |
| What does FIO2 depends on | oxygen input flow, reservoir volume, delivered stroke volume and rate, bag refill time |
| Parts of Bag | patient valve, bag, inlet valve, oxygen nipple, reservoir, pressure pop-off |
| Size of adult bag | 1500-2000 ml volume no pressure pop off needed |
| Size of pediactric bag | 250-500 ml volume Pressure pop off at 40 cmH20 pressure (+-10 required) |
| Size of neonate bag | 250 ml volume comes with 40 cmH20 pressure (+-5 cmH20 pressure pop-off) |
| Ideal stroke volume for Adult | 800 ml avg (1500-2000 max) |
| Ideal stroke volume for infant | 240 ml |
| Spring loaded mechanism | NOT sensitive to patient effort and spontatneous breathing WILL NOT open valve to allow patient to breath from bag |
| Diaphragm (duckbill) | these valves are flexible and EASILY OPENED by pressure from bag compression, or by the pt spontaneous breathing effort |
| Diaphragm (leaf) | spontaneous breathing WILL open valve to allow patient breath from bag |
| Charcteristics of good self inflating bag | Easy to clean..standard connections...self inlfating.. nonrebreathing valve...available in different sizes |
| Function of pop off valve (pressure relief valve) | prevents delivery of excessive pressure with infants/pediactrics pts. |
| Effect of ventilation on RATE | Faster=lower FiO2.....Slower = increased FiO2 |
| Effect of ventilation on O2 FLOW | higher the flow = increased FIO2 slower the flow = decreased FIO2 |
| Effect of ventilation on Reservoir capacity | no reservoir = 35-40 % at O2 flow of 10-15 lpm...up to 100% at O2 flow of 10-15 lpm... size of reservoir = increased size - Increased FIO2 reservoir present = |
| Effect of ventilation on REFILL TIME | increased time = increased FIO2 decreased time = decreased FIO2 |
| Effect of ventilattion on STROKE VOLUME (squeezing) | increased stroke volume = decreased FIO2 decreased stroke volume = increased FIO2 |
| Observations to assure ventilation | rise and fall of chest, breath sounds, ABG, and oximetry |
| Hazards with bags | gastric insufflation, vomiting/aspiration, barotrauma, hypoventilation |
| What to do if you get gastric insufflation | intubate ASAP |
| what to do if vominting or aspiration occurs | intubate ASAP, this causes decreased compliance (expansion stiffens) |
| What to do if barotrauma happens | don't squeeze bag until pop-off--slow down and not as hard |
| what to do if hypoventilation occurs | use both hands, and check for breath sounds |
| Advantage for mouth to mask ventilation | no direct person to person contact |
| Limitations for mouth to mask ventilation | maintain airtight seal, gastric inflation |
| Demand valve | gas powered, pressure relief set at 40, you get 100% FIO2 with 50 psi outlet, THEY CAN GENERATE A BREATH |
| PEEP valves | used to keep back pressure open...pressure to overcome refractory hypoxemia (decreased FRC) (it's not responding to oxygen help |
| Hazards for demand valve | barotrauma because you won't feel compliance, tank runs out to fast, limits pop, don't know tidal volume |
